Re: [Emc-users] Milling Aluminum.

Do test runs in wood or machinable wax or plastic. Could try spraying a dry graphite film on the cutter. NAPA auto parts has spray cans of that. Don't mill the crappy aluminum alloy. On Thursday, April 13, 2017, 8:46:03 AM MDT, Todd Zuercher wrote:Here I go again.

Re: [Emc-users] Milling Aluminum.

What I'd do is have the holes rough cut on a CNC plasma table (they can cut aluminum, with the right setup) then do full depth profile cuts with the wood router gantry. A lot of those cuts, just past the point of chip thinning.

Yes, WD40 works well on aluminum. I'm betting your wood mill is not nearly rigid enough to cut metal. What most people did early on was use a manual Bridgeport type knee mill with hand cranks. Doing this it is easy to see and feel how it works. With my small mill I use an order of magnitude

Re: [Emc-users] Milling Aluminum.

Yuck, if I don't ever have to mill that crap again it will be too soon. Started out dry and trying to mill .12 deep per pass. 1st try (1" long ramp in) tool ramped in to full depth nicely and then promptly snapped, 400imp @18krpm is too fast. 150imp went about 2 inches, gumming up badly.

Re: [Emc-users] Milling Aluminum.

Are you cutting discrete parts out of the plate? IOW, will you end up with multiple parts? Is the support surface flat? Can you cut almost all the way through and leave a .004/.006 membrane holding all the parts together? I would use a reverse helix end mill to have the cutting force push the

Re: [Emc-users] Milling Aluminum.

I got a bunch of scrap pieces of MIC-6 from a local scrap dealer for pretty cheap so I have been making chips and widgets out of it for a while now. It is dimensionaly stable but it does like to chip weld even more than 6061. Another little note about MIC-6 is that if you are cutting the last

Re: [Emc-users] Milling Aluminum.

MIC-6 is particularly gummy when machining. I always use coolant and I still get a little bit of chip weld if things aren't just right. Getting the chips out of the slot you are milling is also critical. I would keep using the compressed air blast and i would probably use a HSM slot instead of

Re: [Emc-users] Milling Aluminum.

The key to milling aluminum dry is cutting a chip big enough to pull the heat out with the chip. So big chips mean the part stays cool, and small chips means the tool will gum up and stick the aluminum. I like 2 flute carbide from Lakeshore Carbide. They make end mills for steel and aluminum
